Arlington Family Mourns Death of North Texas Marine

Smith served three tours of duty before returning to North Texas for college. He still wanted to serve, so he enlisted in the reserves to help for school.

"He gave everything 150 percent, no matter what it was -- whether it was welcoming a new brother to the family, whether it was being there for his Marines -- he did everything 150 percent," said Tyler Schulte, Smith's brother.

The Marine Corps has not released any other information on his death, saying it is under investigation. However, Smith's family said the U.S. Marine Corps gave they a report saying he was killed by friendly fire.

Smith was a light armored crewman who first joined in 2003, the Marine Corps said.
